Professor Peter Bernhardt

is the head of the research group PhONSA and is employed at the institute of Clinical Sciences, the department of radiation physics and as a chief medical physicist at Medical Physics and Technology (MFT) working within the discipline of nuclear medicine. His research has been aimed at treating cancer with radioactive pharmaceuticals. He received his PhD in 2000 and became a docent in 2005. 

Tobias Rydén, PhD

is a medical physicist, with a special interest in programming and software development. He is the developer of PhONSAi with SARec and PhONS-AI included. His major research is within nuclear medicine imaging and analysis. PhONSAi is the research image platform of PhONSA that consists of SPECT reconstruction algorithms, Monte Carlo code, deep learning, image processing etc. All algorithms in PhONSAi are GPU based and written in CUDA and the most compute intensive are written in such a way that they utilize all GPUs in the system with an almost linear scaling.

Jakob Heydorn Lagerlöf, PhD

is a medical physicist, with a background in experimental physics and automotive engineering. He has been working with R&D in various contexts since 2001, with a particular interest in mathematical modelling. He has taught primary school, postgraduate and everything in between and is very interested in popularisation of science. Jakob is currently MRI physicist at Örebro University Hospital and adjunct associate professor at the Sahlgrenska academy. His major research interest is within radiophysical and radiobiological modelling.

Emma Wikberg (MSc)

is a medical physicist working in the field of nuclear medicine at Sahlgrenska University Hospital. Right now, she is dividing her time between the clinic, mainly pediatric nuclear medicine at Queen Silvia’s Children Hospital, and PhD studies focusing on analysis techniques and image quality in nuclear medicine images.


Linn Hagmarker (MSc)

is currently working as a PhD student in the research group PhONSA at the department of Radiation Physics. She has a Master of Science in Medical Physics. Her field of research is radionuclide therapy, developing a method estimating the absorbed dose to the bone marrow during 177Lu-DOTATATE treatments.


Jens Hemmingsson (MSc)

joined the research group after his graduation in 2015 and went working on microsphere simulations in radioembolization and Monte Carlo reconstructions in SPECT images. As a PhD student his current research is within radioembolization, looking to describe post-therapeutic microsphere distributions.


Ida Marin (MSc)

has a Master of Science in medical physics. She joined the PhONSA group when writing her master's thesis, in which she investigated radiation dose and tumor response after treatment with 177Lu-DOTATATE. She is currently working as a research associate.
